Hi!
I think you mean the preFunc of the GeoState. This preFunc is called after
Performer has applied the GeoState.
(At least) to me it is not always clear whether Performer did really apply
your texture. If I remember correctly you need to have a textured geometry,
otherwise it simply does not apply it.
To be sure that the texture is really applied just call
if (!texture->isFormatted()) texture->apply(); // this will do a
// texture->format()
then the GL handle should be valid.
Best,
Alex
